IMPROVEMENT IN MACHINERY FOR SPOOLING THREAD.

Specification forming part of Letters Patent No. 50,575, dated October24, 1865.

To all lwhom it may concern:

Be it known that I, A. B. GLoVER, of Yonkers, in the county ofNVestchester and State of New York, have invented a new and usefulImprovementinlilachines for SpoolingThread; and I do hereby declare thatthe following is a full, clear, and eXact description thereof, whichwill enable those skilled in the art to make andnse the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure lis an elevation of a spooling-machinemade according to my invention. Fig. 2 is an elevation of across-section taken on the line y of Fig. I. Fig. 3 is an elevation of across-section taken on the line oo of Fig.l. Fig. 4 is a plan of asection taken on the horizontal line z of Fig. l.

Similar letters of reference indicate corresponding parts.

The object of this invention is to produce a spooling-machine which willwind a spool of silk, cotton, or other thread automatically and stop theinstant the spool is full. Among other novel features in itsconstruction is the mode of disconnecting the spindle from the shaft orpulley which drives it 5 also, a peculiar construct-ion of a slide whoseposition determines the distances to be traveled by the thread-guide inlaying the courses of thread on the spool.

A designates the-frame of the machine.

C is the spindle, upon the front end of which the spool to be wound isplaced. H is a friction-pulley upon said spindle. It is driven by meansof frictional contact with the large pulley B of the shaft B directlybeneath.

1) is a traverse-rod, placed at about the same height as the spindle,and carrying on its front end, beyond the frame, a thread-guide, d,ofthe usual construction. The spindle C, shaft B, and traverse-rod'Dhave their bearings in the sides of the frame A. E is a shaft, alsorunning in the said frame, which has out thereon right and left handscrew-threads. The traverse rod D carries a pendent frame, F, which is'curved where it passes the shaft E, so as to pass without touching it.This frame carries two half-nuts, f f', at opposite ends and dit'-ferent sides, one of which,f, is seen above theI plate L. The other, f',is concealed bythe screw-threaded shaft, but its place is indicated inred outline above the plate K. These nuts have screw-threads cut ontheir inner faces to match the screw-threads of the shaft E, with whichthey are brought in contact in alterna-- tion, as hereinafter explained.

K is a plate, extending downward from the lower edge ofthe swingingframe, near its lefthand, side far enough to be able to engage the teethof the cogged wheel It when it takes a position over that wheel. Thelower left-hand corner of said plate is beveled oft' to enable it thebetter to enter between its teeth .when the wheel is to be moved. Lisanother plate, also extending downward from the lower edge of the frameF, but near its opposite end. This plate terminates in an angle thesides ot' which are equal. Its length and position are such as to enableit to engage with the angular npper end of a slide, I, which is moved upand down at certain times in a stand, J, secured to the floor of themachine.

Gr is a shaft, also turning in bearings in the sides of the frame A. Itsplace is beneath the shaft E, and it passes through the upper part ofthestand J, and carries a snail-shaped cam, g, which rotates between thesides of the stand and in a vertical slot cut for it in the slide I,

(see Fig. l.) The outline of the cam is seen in Fig. 2. Its rotationgradually lifts the slide, and so elevat-es its angular top more andmore past the angular end of the plate L, the effect of which is tocause that plate to have a longer traverse across the faces of theslide, as hereinafter mentioned. The shaft G carries also a toothedwheel, h, whose place is beneath the middle of the lefthaud screw-thread of the shaft E. A snail-shaped cam, p, is xed on the the shaft nearits left-hand end. (See Figs. l and l and the dotted outline thereof inFig. 3.) This cam acts upon the lower end of a latchbar, N, to throw itont of its engagement with the long end of a lever, O, (seen mostclearly in Fig. 3.) The right-hand side of the frame supports a bracketor table, T, which projects inward over the slide I, and is divided intotwo parts, one of which is on either side ofthe change-plate L. Eachpart of said bracket carries a finger, (designated r r,) which are keptpressed inward toward the change-plate by the opposite ends of atwo-armed spring, s.

' it is thrown when the pulley B is lowered,as

O is a three-armed lever, secured by a screw to the inside of the backend of the machine, the short end of which supports the bearing of theadjacent end of the shaft B. The long end of said lever extends towardthe latch N, which swingsI against and engages it when the long arm ofsaid lever has been brought down by means of the treadle-connecting rodU, thereby holding the bearing of the shaft in its highest position andbringing its friction-pulley B into contact with the pulley H on thespindle C. The lever O is released from. the latch N whenever the toe ofthe cam p reaches the latch and pushes it outward, by which action theshaft B is lowered and the pulleys B and H are separated, so that thespindle C ceases to revolve. O is the upper one of the three arms of thelever O. Itis bent so as to form a friction-brake for the pulley H,againstwhich above explained, so as to instantly stop the movement ofthe spindle.

The shaft B is extended through the lefthand side of the frame A,outside of which it carries a driving-pulley, b. The spindle C and theshaft E also extend beyond that side ofthe said frame, the formercarrying a small pulley, c, which drives a larger pulley, e, on the endof shaft E, by means of a belt. When the swinging frame F hangsvertically neither of the sectional nuts ff are in contact with theright or left hand screws; but when swung to the right far enough forthe lower point of the plate L to pass the top of the slide I, (see Fig.2,) the sectional nut fis thrown into connection with the right-handscrew-thread, which moves the nut, and consequently the frame F and thechange-plate L, from left to right. The traverse-rod D is free. to moveendwise in the frame A, and the frame F is rigidly collnected to saidrod, and therefore the rod D and its thread-guide el are moved to andfro with said frame F. As the plate L is moved forward past the slide Iit comes in contact with the bent nger fr', which it forces back againstthe spring s, the pressure of which acts to crowd the plate L againstthe slide I, so as to swing it, with the frame F, across to the otherside of the opening in the bracket T, so soon as it passes the angularside of the slide toward which it was moving, thereby disengaging theright-hand screw-thread from the sectional nut j', and engaging theleft-hand screwthread with the sectional nut f', for a returnmovement ofthe traverse-rod and its threadguide, and at the same time the swingingframe, having been moved far enough to the left to bring the plate Kinto engagement with the teeth of the wheels h, causes the plate K, asthe frame is moved to the other side of the slide I, to rotate the wheelthe distance of one tooth. On the return of the swinging frame towardtheright the plate K leaves the wheel, and when the plate L has againpassed the slide I the said frame, with its plate K, is

swung to the other side of the slide by means of the spring s on arm i",so that upon the neXt movement of the plate K toward the left itsbeveled edge enters between the next two teeth of wheel h, and againcauses it to move the distance of one tooth. The rotation of the wheel hcauses the shaft G and its cam g to be rotated, thereby raising theslide I so that its top overlaps the plate L more and more at eachmovement of the wheel h, and thus compelling the plate L to travelfarther before it can pass it, and consequently making the traverse-rodD and its thread-guide d to move a little farther each way. rllherotation of the shaft Gr also gradually rotates the cam 1J with the samespeed as the cam g. These movements continue until the cam g has made acomplete revolution, at which time the slide I drops off the toe a ofthe said cam, and the toe of the cam p comes in contact with the latch Nand forces it out of engagement with the lever, so that the pulley B islowered out of contact with the pulley H, and the brake O' falls againstthe latter, when the machine stops. The shaft B is driven by a belt uponits pulley b, and'runs continually, whether it is raised so that itsfriction-pulley is in contact with the pulley H of the spindle or not.The operator places a spool upon the right-hand end of the'spindle,after having started a thread upon it from a bobbin in some convenientplace through the eye in the thread-guide d, and lets the threadguidedown upon the spool. He then depresses the long end of lever O by meansof the treadlerod U,until it is caught by the latch N, thereby raisingthe pulley B into contact with the spindle-pulley H, and giving motionto the spindle. Motion is communicated from the small pulley c yof thespindle to the pulley e of the shaft E by means of a belt, (seen inFigs. 1, 2, and 3,) and the motion of the last-named shaft iscommunicated to the traverse-rod D by means of the sectional nuts andswinging frame, causing it to reciprocate, as above described, thedistance of its traverse gradually increasing for each upward movementof the slide I, so that the thread-guide may bring the thread up to theinclined sides of the spool, and the threadl shall be evenly laidthereon. These movements are continued through the alternate connectionof the sectional nuts with the ri ghtandleft hand screw-threads, theplate Krotating the wheel h the distance ofone tooth upon every returnuntil the shaft G, with its cams g and p, has made a completerevolution, at which time the cam p stops the operation, as aboveexplained, the machine having wound twice as many courses of thread uponthe spool as there are teeth in the wheel h. The full spool is thentaken off, an empty one put on, and the operation is begun again.

I claim as new and desire to secure by Letters Patent- 1. In machinesfor spooling thread, the lever O, constructed and operated substantiallyas above described, one arm of which carries one end of the main shaftB,and another is engaged at cert-ain times by a 1atch,N, as herein shown.

2. The slide I, constructed substantially as shown, in combination witha change-plate, L, substantially as above described.

3. The combination ot' the cam g with the slide I, substantially asabove described.

4. The iingers r r, in combination with the change-plate L,substantially as above described, the fingers being pressed continuallyagainst the plate by a spring, s, or other suitable devices.

5. The toothed wheel h, in combination with il ir il above described.
